Umbilical Pilonidal Sinus: A Report of Two Cases and Recent Update of Literature.

Umbilical Pilonidal Sinus (UPS) is a rare differential diagnosis of umbilical disease as encountered by general surgeons. They usually present with history of pain and umbilical discharge. Young active adolescent males with dense hairy abdomen with a deep naval are at risk of developing this disease. There are no consensus guidelines for the management of this disease probably because of its rarity. Treatment depends on the type of presentation. Most of the cases are managed by conservative treatment with hair extraction and personal hygiene. Surgery is indicated in case of failure of conservative management. Although umbilectomy is a commonly done procedure, complete sinus excision with reconstruction which can be done to have better cosmesis. Incomplete hair extraction from the sinus tract has been found to be the commonest cause of failure of conservative management. In this paper we have presented two cases of UPS, managed conservatively, with no recurrence after one year of follow-up. We have also presented a recent update on current literature about this uncommon disease.
